Microscope . Small structure of the cells can look into for a microscope... This part regulates the amount of light on the specimen
Potential difference is energy per coloumb of charge so energy = vq
energy = 1.5 * 9000 = 13500 J
Answer:
Cystein, threonine and tryptophan can form hydrogen bond with progesterone
Explanation:
Those amino acids have -OH or H subunit in their side chain and these moities are very esential for hydrogen bond formstion with progesterone
A hydrogen bond can be said to be a partial intermolecular bonding between a lone pair on an electron rich donor atom, particularly highly electronegatine elements like nitrogen, oxygen, or fluorine and the antibonding orbital of a bond between hydrogen (H) and another more electronegative atom or group. Dotted or dashed line is always used to indicates the hydrogen bond.
Hydrogen bonding can also be seen existing between water molecules or hydrogen fluoride molecules since each molecule contains hydrogen bonded to a hyghly electronegative element.
When mass Ti = density * volume
and when moles Ti = mass Ti/molar mass Ti
∴ Volume = 2.86 x 10^23 atom * ( 1 mol Ti / 6.022 x 10^23) * (47.867 g Ti / 1 mol Ti) *(1Cm3 / 4.5 g Ti )
= 5.05 Cm^3
when we assume that the sample of Ti is a cube:
and we assume the length = X
∴ V = X^3
∴X^3 = 5.05
∴X = ∛5.05
= 1.7 Cm
the tide is small then normal because the gravitational fore of the sun and moon pull in the same direction
